Method for Calculating the Sound Absorption Coefficient for a Variable Range of Incidence Angles by Sergio Alfio YORI

“…Absorption coefficients for normal and diffuse sound fields are widely known, although they may be far from the absorption values given by an absorbing material when it is finally installed inside a room or enclosed space, where a sound field closer to a spherical wavefront is more likely to be found. This work presents a theoretical study, which is addressed at obtaining a mathematical expression to calculate the sound absorption coefficient for a variable range of incidence angles, called $α_s$. …”

Numerical Reduced Variable Optimization Methods via Implicit Functional Dependence with Applications by Christopher Gunaseelan Jesudason

“…A systematic theoretical basis is developed that optimizes an arbitrary number of variables for (i) modeling data and (ii) the determination of stationary points of a function of several variables by the optimization of an auxiliary function of a single variable deemed the most significant on physical, experimental or mathematical grounds from which all the other optimized variables may be derived. …”

Adapting to Climate Variability: The Role of Environmental Factors in Crop Yield Stability in Turkiye by Muhammed BENLİ

“…Using the Autoregressive Distributed Lag (ARDL) bounds testing methodology with time series data from 1981 to 2020, we investigate both short-term and long-term relationships between these environmental variables and crop yields. Our findings reveal that barley yields exhibit a cointegration relationship with climatic factors, indicating a stable long-term equilibrium, while pea shows no such enduring association, suggesting it is more sensitive to short-term fluctuations. …”

Gear Pump Versus Variable Axial Piston Pump in Electro-Hydrostatic Servoactuators by Alexandru Dumitrache, Liviu Dinca, Jenica-Ileana Corcau, Adriana Ionescu, Mihai Negru

“…The gear pump EHA has a simpler mechanical configuration, but the electronic power command circuits and the electric motor are in high demand due to the very frequent speed variations. The variable piston pump EHA has a more complicated mechanical configuration, but the electronic power command circuits and the main electric motor are less loaded due to the constant speed of the electric motor. …”
